Healthy Bed for Actively Supporting Human Spine Curve

ABSTRACT

A healthy bed for actively supporting human spine curve mainly comprises a lower base, a mobilizing device inside the lower base, a height sensor, a control device, an inflating device, an upper mattress having an air cushion layer and a plurality of push rods wherein the control device is used for memorizing the spine curve of a person lying on the upper mattress. When a user lies on the upper mattress, the push rod is pressed to push the mobilizing device moving downward, the height sensor detects a moving distance of the mobilizing device for the control device to determine whether the user is the one whose spine curve is memorized, if so, then the inflating device is activated to inflate the air cushion layer to let the surface of the upper mattress meet the profile of the spine curve of the user.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a healthy bed for actively supporting human spine curve, and more particularly, to a healthy bed for actively supporting human spine curve, which can memorize a spine curve of a user lying on the bed, when the user lies on the bed again, the healthy bed can actively support the spine curve through air cushions to achieve the best sleep quality.

2. Description of the Prior Art

In modern developed society, workers could suffer from high work pressures and have insomnia problems, and bad sleep quality could lead to anxiety, depression, headache, muscle soreness, burnout, palpitations and hair loss. Therefore, manufacturers have developed various mattresses such as healthy mattress, memory foam mattress, and energy mattress, which claim to improve sleep qualities. However, the traditional mattresses use spring to bear the weight of users, they can not actively support the users to relieve their stresses, and the insomnia problems still persist.

Therefore, in order to solve the above problems, the applicant of this invention has already filed PCT applications PCT/CN2007/0002585 (citation 1), PCT/CN2007/002602 (citation 2), and PCT/CN2007/002956(citation 3), which are described below:

Citation 1 discloses a healthy bed which can adjust the human spine curve, the healthy bed comprises a plurality of lifting devices, each lifting device is driven by motor to lift and lower the independent bed tubes of the mattress so as to let the mattress form a profile corresponding to human spine curve to actively support the user. However, the motor driven means needs to use a lot of motors and the costs are high, making it difficult for massive applications.

Citation 2 discloses another healthy bed which can adjust the human spine curve, the healthy bed comprises a plurality of lifting devices, which uses air bags or water bags to lift and lower the independent tubes of the mattress so as to let the mattress form a profile corresponding to human spine curve to actively support the user. However, this application needs to use a lot of air bags or water bags, which can be complicated to implement and the costs are high, making it difficult for massive applications.

Citation 3 discloses another healthy bed which can adjust the human spine curve, the healthy bed comprises a plurality of lifting devices, each lifting device comprises a base with a slot disposed at a front end of the base, both sides of the slot are fixed with a elastic body, the two elastic bodies support the two ends of the mobilizing rod to let the mobilizing rod move up and down through the elastic forces of the elastic bodies; a height sensor is disposed in the side wall of the slot to detect the moving distance of the mobilizing rod; more than one air cushions are disposed on the based, each air cushion comprises a sensing bar extending from its top to reach the mobilizing rod, and the air cushion is connected with an air pump, the air pump and the height sensor are coupled with a control device. When the air cushion is pressed by a user, the sensing bar is lowered, and the mobilizing rod is pushed downward with a distance, then the height sensor detects the lowest position of the mobilizing rod and transmits the detection result to the control device, then the control device will determine if the person lying down is the user, if so, then the air pump will inflate the air cushion according to the detection result received by the control device to actively support the spine curve of the user to improve sleep quality. Citation 3 has all the components built in the mattress; however, the bed is too bulky and too heavy to handle.

Therefore, the traditional healthy beds present several shortcomings to be overcome.

In view of the deficiencies of the traditional healthy beds, after years of constant researches, the inventor has consequently invented and proposed a healthy bed for actively supporting human spine curve.

Please refer to FIGS. 7A and 7B, and FIGS. 8A and 8B for operational views of the healthy bed for actively supporting human spine curve in the present invention. When a user 8 lies on the upper mattress 6 for the first time, the supporting air bags 622 in the upper mattress 6 correspond to the neck vertebrae, thoracic vertebrae, lumbar vertebrae, sacral vertebrae, hip and the legs of the user 8, at this time, the supporting air bags 622 are not bloated, and the push rods 63 of the upper mattress 6 will be pressed by the weight of the user 8, since each push rod 63 bears different weight, the moving distance of each push rod is different from one another, the push rod 63 bearing the heaviest weight will push the mobilizing rod 23 of the mobilizing device 2 downward, so the mobilizing rod 23 will be in contact with the height sensor 3 to let the height sensor 3 detect a moving distance of each mobilizing rod 23 when it reached the lowest position, therefore the spine curve regards to the neck vertebrae, thoracic vertebrae, lumbar vertebrae, and sacral vertebrae of the user 8 will be determined, and the detection results will be sent to the control device 5 for storage, then the control device 5 will know the air volume of the supporting air bags 622 corresponding to the neck vertebrae, thoracic vertebrae, lumbar vertebrae, and sacral vertebrae of the user 8.

Besides, the control device 5 memorizes spine curves of the user 8 for various sleeping postures in advance and supports the spine curves of the user 8 when he/she is changing sleeping postures.

When the user 8 once again lies on the upper mattress 6, which memorizes the spine curve, the control device 5 detects the moving distance of the mobilizing rod 23 to determine if the person is the user 8, if so, then the control device 5 activates the control switches 9 to inflate the supporting air bags 622 respectively through the inflating device 4 if necessary, when a supporting air bag 622 is inflated to a predetermined volume, the control device 5 will deactivate the corresponding control switch 9, since each control switch 9 has different activating and deactivating times, the upper mattress 6 will form a profile corresponding to the spine curve regarding to the neck vertebrae, thoracic vertebrae, lumbar vertebrae, and sacral vertebrae of the user 8 through the supporting air bags 622, and the supporting air bags 622 will fill the space between the neck vertebrae, thoracic vertebrae, lumbar vertebrae, and sacral vertebrae of the user 8, and the bed will actively support the human spine curve. So when the user 8 is lying on the healthy bed, he/she can get the best support and the best sleep quality.

When the user 8 leaves the upper mattress 6, the push rod 63 moves upward, the mobilizing rod 23 returns to its original position due to the elastic force of the elastic body 22, then the height sensor 3 detects the returning movement of the mobilizing rod 23 and sends the detection signal to the control device 5, the control device 5 drives the inflating device 4 to deflate the bloated supporting air bag 622 to let the top surface of the upper mattress 6 become flat again.
